Integral Abutment Bridges (IAB) are defined as simple or multiple span bridges in which the bridge deck is cast monolithically with the abutment walls. IAB is also called as joint less bridge. The main purpose of constructing IAB’s is to pre-vent the corrosion of the structure due to water seepage through joints. They improve aesthetics and earthquake resistance towards the traditional systems with expansion joints, roller supports, and other structural releases which permit thermal expansion and contraction, creep, and shrinkage. In this paper total four models are compared two with considering soil interaction and other without soil interaction and live load is applied using MIDAS CIVIL. First model is taken straight IAB without soil interaction and second straight model with soil interaction, third model curve IAB without soil interaction and fourth one curve with soil interaction. The paper motive is to study the trends in bending moment, shear force and deflection in central and end girders and deck slab due to dead load, live load with combination of thermal loads.

Keywords: Integral Abutment Bridges, Thermal expansion, Contraction, creep, Shrinkage etc.
